How many hired servants of my father’s have bread enough and to spare. – Luke 15:17

If we could call forth from his seat a weak believer in God, who is almost unknown in the church, one who sometimes questions whether he is indeed a child of God, and would be willing to be a hired servant so long as he might belong to God, and if I were to ask him, “How, after all, has the Lord dealt with you?” what would be his reply? You have many afflictions, doubts and fears, but have you any complaints against your Lord? When you have waited upon Him for daily grace, has He denied you? When you have been full of troubles, has He refused you comfort? When you have been plunged in distress, has He declined to deliver you? The Lord Himself asks, “Have I been a wilderness unto Israel?” Testify against the Lord, ye His people, if ye have aught against Him. Hear, O heavens, and give ear, O earth, whosoever there be in God’s service who has found Him a hard task-master, let him speak. Amongst the angels before Jehovah’s throne, and amongst men redeemed on earth, if there be any one that can say He hath been dealt with unjustly or treated with ungenerous churlishness, let him lift up his voice! But there is not one. Even the devil himself when he spoke of God and of his servant Job, said, “Doth Job serve God for nought?” Of course he did not: God will not let His servants serve Him for nought; He will pay them superabundant wages, and they shall all bear witness that at His table there is “bread enough and to spare.” Now, if these still enjoy the bread of the Father’s house, these who were once great sinners, these who are now only very commonplace saints, surely, sinner, it should encourage you to say, “I will arise and go to my Father,” for His hired servants “have bread enough and to spare.” ~ C.H. Spurgeon
